The function LaTeX: f\left(x\right)=2x^2+x+5f ( x ) = 2 x 2 + x + 5 represents the number of jars of pickles, y in tens of jars, Denise expects to sell x weeks after launching her online store. What is the average rate of change over the interval 1 ≤ x ≤ 2? Group of answer choices

Ahigh-altitude spherical weather balloon expands as it rises, due to the drop in atmospheric pressure. suppose that the radius r increases at the rate of 0.02 inches per second, and that r = 36 inches at time t = 0. determine the equation that models the volume v of the balloon at time t, and find the volume when t = 360 seconds. v(t) = 4π(0.02t)2; 651.44 in3 v(t) = 4π(36 + 0.02t)2; 1,694,397.14 in3 v(t) = four pi times the product of zero point zero two and t to the third power divided by three.; 4,690.37 in3 v(t) = four pi times the quantity of thirty six plus zero point zero two t to the third power divided by three.; 337,706.83 in3
